https://bugzilla.kernel.org/show_bug.cgi?id=101241 Bug ID: 101241 Summary: cpufreq ondemand not work in my system Product: Power Management Version: 2.5 Kernel Version: 2.6.32 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: cpufreq Assignee: cpufreq@xxxxxxxxxxxxxxx Reporter: jakepain@xxxxxxxxx Regression: No I want to use cpufreq "ondemand" policy to change the CPU frequency dynamiclly. But when I insmod the powernow-k8 driver, it detected below data Jul 9 11:11:43 localhost kernel: powernow-k8: Found 1 AMD GX-416RA SOC (4 cpu cores) (version 2.20.00) Jul 9 11:11:43 localhost kernel: powernow-k8: 0 : pstate 0 (1600 MHz) Jul 9 11:11:43 localhost kernel: powernow-k8: 1 : pstate 1 (1600 MHz) Jul 9 11:11:43 localhost kernel: powernow-k8: 2 : pstate 2 (1600 MHz) Jul 9 11:11:43 localhost kernel: powernow-k8: 3 : pstate 3 (1600 MHz) Jul 9 11:11:43 localhost kernel: powernow-k8: 4 : pstate 4 (1600 MHz) Jul 9 11:11:43 localhost kernel: powernow-k8: 5 : pstate 5 (1600 MHz) Why the CPU frequency is fixed? is it caused by BIOS setting? Is there some methods to modify the limit in software not BIOS?
